Mã hàng: KSMH2.TC
Xuất xứ: Thái Lan
Kumwell KSMH2.TC series of surge protective devices has been developed to protect against the effects of induced voltages onto data, signal and communication circuits.
Like the KSMH-TC series, the KSMH2-TC provides the same level of pro-tection to two independent circuits (pairs). A number of protection voltages are available to ensure the user is able to select the closest clamping vol-tage to the normal signal operation of the equipment being protected.
